This paper proposes to extend this set of causality assignment procedures. The proposed alternative procedures are mainly inspired by formulations developed in the mechanical domain. They enable Lagrange equations, Hamilton equations and Boltzmann-Hamel equations, as well as formulations with the Lagrange multipliers, to be obtained.
After a brief introduction of bond graphs and the causality concept, section 2 presents the three initial procedures (SCAP, LCAP, RCAP) with their modified versions (MSCAP, MLCAP, MRCAP). Section 3 goes through the alternative proposed procedures in detail. Section 4 deals with examples for the application of the alternative procedures proposed. Finally the conclusion shows the important features of such alternative causality assignment procedures on the use of bond graph language.
